hello/bonjour
I've noticed that the mars place names were neither the WW 1.3.5 nor in the WW 1.4. But... you can see them. I think there is a better method but the following one seems to work.
First download "mars off line add-on.exe" (on WorldWindCentral Site). Run the .exe and specify the path. This one must be a specific folder (NOT the usual path for WW download), for instance « mars tempo », on your desk . Then open it. Click on the config folder, then click on mars folder, you'll find the ^placenames file (xml). Copy it in c:\program files\nasa\worldwind 1.3.5 (or 1.4)\config\mars.
Secondly, see if there is a folder « Mars » in c:\program files\nasa\worldwind 1.3.5 (or 1.4)\Add-ons. Otherwise create it.
Thirdly, in the mars tempo folder (you've dowloaded on your desk), click on « Add-ons» folder, then on « Mars » folder. You'll see a Data folder. Copy it in c:\program files\nasa\worldwind 1.3.5 (or 1.4)\Add-ons\Mars. That's it ! If a developper could write a little programm to do this that would be cool, specially for the poor end-users like me
